► Press the "Gate Delay" softkey.
The R&S ZVH opens an input field to define the trigger delay.
► Enter the delay time you need.
The measurement now starts after the delay time has passed.
► Press the "Gate Length" softkey.
The R&S ZVH opens an input field to define the gate length.
► Enter the length of the gate.
The R&S ZVH now measures over the period of the gate length. After the gate has
closed, the R&S ZVH waits with the measurement until the next gate signal
happens.
The delay time and gate length are represented by vertical red lines in the diagram
area.
► After setting the gate delay and gate length, exit the gate settings menu with the
"Exit" softkey.
The R&S ZVH returns to the frequency domain provided it was active before
setting up the gated trigger. The original span is restored. The R&S ZVH is ready
to perform measurements with an accurately set gate.
4.2.4.4 Selecting the Sweep Type
The sweep type defines the way how the R&S ZVH captures and processes the
data.
► Press the SETUP key.
► Press the "User Preferences" softkey.
► Select the "Sweep / FFT" menu item.
The R&S ZVH opens a dropdown menu to select the sweep type.
Which sweep type is appropriate for the current measurement depends on the
span, RBW, VBW and sweep time settings.
-
Auto
The R&S ZVH automatically selects the fastest sweep type for the current
measurement configuration.
-
Always Sweep
The R&S ZVH uses the local oscillator to provide the spectrum quasi analog
from the start to the stop frequency.
-
Prefer FFT
The R&S ZVH samples the signal levels over time on a defined frequency
value and transforms it to the spectrum by fast Fourier transformation (FFT).
